Ok thx.Yes everything else is all stock. I went with MB Quart because they designed these as a plug and play for the JL and JT so it was pretty easy to do. There's no splicing of wires and they include the wire harness that just plugs into the old speaker wire. Here's all the speakers they offer for the JL/JT. I went with the 3.5" and 6x9". The 6x9" comes with the mounting kit but they do sell that separately if you want to use a different brand of speaker.
I ordered the fronts first to see how good they sound. Then I will go from there.
the wiring would be simple to do as far as that goes.
